I’ve been invited to take a written assessment，There were four problems in total. An easy one: parse a short program that moves a robot up or down and report its final position relative to the origin. A straightforward array-processing task—the algorithm was already spelled out in the statement, so you just had to copy it verbatim. Implement a round-robin load balancer; the only real pitfall is parsing the commands correctly. A twist on LeetCode 1248. Pro tip for C++ users: brush up on substr’s syntax beforehand… once the clock is ticking and your mind goes blank, you’ll end up hand-rolling it.
